Mack Jam

On the left side of the square inch wall locate an overhanging bulge with a single sinker hand jam above it. Do a boulder problem up to the Jam and get your first piece, then continue up easier terrain trending right towards the arete feature above. The 9+ is the unprotected start.

"The Notches" describes this as a hand crack, I'd say its more of a pod for a hand jam and a placement.
